Multiple SSH Keys settings for different github account

create different public key

Make sure you have .ssh folder created:

$ mkdir ~/.ssh
$ chmod 700 ~/.ssh

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "your_email@youremail.com" -f "key-name"

Please refer to github ssh issues for common problems.

for example, 2 keys created at:

~/.ssh/id_rsa_github
~/.ssh/id_rsa_bitbucket

then, add these two keys as following

Make sure that the ssh-agent is running:

eval `ssh-agent`

$ ssh-add ~/.ssh/id_rsa_github
$ ssh-add ~/.ssh/id_rsa_bitbucket

you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ subl -a config

Then added

# GitHub account
Host github.com
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_github

# Bitbucket account
Host bitbucket.com
	HostName bitbucket.com
	User git
	IdentityFile ~/.ssh/id_rsa_bitbucket

Setup the SSH in the service of your choice:

• GitHub
• Bitbucket

After that, check if everything is ok:

• GitHub: ssh -T git@github.com
• Bitbuket: ssh -T git@bitbucket.org
